- I translated on my forum part of a very interesting letter of R. Descartes (1638) in which he explains that one must exclude Time and Speed in the question of Force (Energy). Why? Because if you keep Speed and Time, you have to solve Metaphysical problems that Descartes does not want to solve in an essay about Ballistic or Statics.
Make the comparison with Scientists on this forum (Carlo Rovelli) who are face to face (350 years after) with the same problem. They suggest to forget time like Descartes, but, the 'nonsense' is here : they keep the Time as a dimension!!!
- No doubt that Poincaré, Einstein and H. Bergson when they are introducing Time are fighting against Descartes empiricism and want to introduce first of all Metaphysics that is for them related to Time idea (Music gives you the feeling that Time existe out of your Mind.)
- I am not only making the link between science and art but between Politics too. Mirror (of Japanese Emperor) is grounding the Christian Culture of Descartes, Huygens and Newton. French King Louis XIV was a kind of Japanese Emperor too. Do you think it is just a coincidence if Statics principles are triumphating in Europe just when State Religion is triumphating in England and France?
Statics in Art, statics in Science and statics in Politics at the same Time!
